I’m glad you enjoyed your pretty walk. I love other people’s flowers, too, as I don’t enjoy gardening either.
In my house before this one I had flowers on my deck. It got shade most of the day, but intermittent sun. I like container gardening and that’s what I had on my deck. The backyard went down a slope to a creek, then up a steep hill on the other side of the creek. No houses behind us, just woods. I loved it. I was one of the few in the neighborhood who loved all the deer going through. (Those fawns were awesome!). In my current house with no shade I can’t grow hardly anything, but my neighbors can. I don’t get it!
Improvement in bend is going to take time. It took me months! Then at 4 months I had a major set back and my ROM was awful for months after. I was back to having that really tight feeling in my thigh and especially the back of my calf. For months. It finally eased up gradually and my bend, even now at 16 months, is better than ever. In spite of my other issues.
Your only about 4 weeks. Give it time. Stretches are good, but not if they hurt. If they do, it’s too much at this point. Give it time and try a little more of a stretch later.
